You’re standing on the shore of Lake Wyndamer. It’s foggy. The air feels heavy, like it’s holding its breath, and right there in the middle of the water sits Fyke Isle. If you've played The Witcher 3: Wild Hunt, you know exactly what I’m talking about. A Towerful of Mice isn't just another contract on a notice board; it’s the moment the game stops being a fun monster hunt and starts being a psychological nightmare.
Honestly, it’s the atmosphere that gets you first.
Most players stumble into this quest because Keira Metz—the sorceress who’s clearly too sophisticated for the mud of Velen—wants a favor. She gives you a magic lamp and tells you to go check out a cursed tower. Sounds simple, right? It never is. Not in this game. This quest is a masterclass in environmental storytelling, and it serves as the perfect introduction to how CD Projekt Red handles choice and consequence.
The Grim Reality of Fyke Isle
Fyke Isle is a dump. Let’s be real. It’s crawling with rotfiends, drowners, and water hags that want to rip Geralt’s face off. But the real horror isn't the stuff trying to kill you in the bushes. It’s the ghosts.
When you use Keira’s lamp, you see green, flickering silhouettes of the past. These aren't just random spirits; they’re the echoes of a starving peasantry that decided they’d had enough of the local lord’s greed. They stormed the tower. They wanted food. They wanted blood. What they got was a massacre.

What makes the A Towerful of Mice quest so effective is the pacing. You climb the tower level by level. Each floor reveals a bit more of the tragedy through the lamp and the journals left behind. You find out about Alexander, a mage who was supposedly working on a cure for the plague. But, as Geralt quickly deduces, his "research" involved some pretty unethical stuff involving rats. Lots and lots of rats.
Then you meet Anabelle.
She’s the heart of the quest. A ghost lingering in the top room, she tells a heartbreaking story of being paralyzed by a potion while the peasantry broke in. She had to watch—unable to move a muscle—as the rats began to eat her alive. It’s one of the most gruesome mental images in the entire franchise. You feel for her. You really do. And that’s exactly where the game tries to trip you up.
Why Most Players Get the "Good" Ending Wrong
The Witcher 3 loves to punish you for being a nice guy. If you talk to Anabelle and decide to help her without being suspicious, you’re probably going to get the "bad" ending.

Most people see a crying ghost girl and think, "Yeah, I’ll take your bones to your lover, Graham. That’ll break the curse."
Stop. Think like a Witcher. Geralt is a professional. He knows that ghosts, especially Pesta (plague maidens), are manipulative. If you agree to take her bones off the island immediately, you’re basically smuggling a bio-weapon into the mainland. Anabelle isn't just a victim; she’s become a vessel for the Catriona plague.
If you trust her blindly, you leave the tower, find Graham, and give him the bones. He kisses her spirit, dies a horrific death, and Anabelle vanishes into the world to spread disease. You "solved" the quest, but you've potentially killed thousands of people in the process. It’s a gut-punch.
The "better" path—though "good" is a stretch in Velen—requires Geralt to call her out. You have to notice the inconsistencies in her story. If you refuse to take the bones and instead bring Graham to the tower, the curse is lifted through a "test of love." Graham still dies, but the plague maiden is laid to rest.
It’s dark. It’s messy. It’s peak Witcher.
The Real-World Folklore Behind the Mice
CDPR didn't just pull the "mice eating a lord" thing out of thin air. They drew heavily from the Polish legend of Popiel II, a legendary 9th-century ruler.
The story goes that Popiel was a cruel leader who, egged on by his wife, poisoned his uncles to solidify power. During the funeral feast, a massive swarm of mice emerged from the bodies (or the lake, depending on the version) and chased Popiel and his family to a tower in Kruszwica. They climbed to the top, thinking they were safe, but the mice gnawed through the walls and ate them alive.
By grounding A Towerful of Mice in actual Slavic folklore, the developers gave the quest a weight that feels ancient. It’s not just a spooky story; it feels like a myth you’d be told as a kid to keep you from being a jerk to your neighbors.
Navigating the Quest Like a Pro
If you’re currently standing on that island and sweating over what to do, here is the breakdown of how to handle the situation without ruining the lives of everyone in the Northern Realms.
- Loot everything. Seriously. The tower is full of alchemical ingredients and notes that flesh out the lore. Don't rush to the top floor.
- Use the Magic Lamp constantly. There are hidden dialogues throughout the tower that don't trigger unless you're standing in the exact right spot with the lamp out.
- The Pesta realization. When talking to Anabelle, Geralt can mention that the "fresh" corpses outside don't match her timeline. This is your clue that she's lying.
- The Graham Choice. Bringing Graham to the island is the only way to actually break the curse without letting a plague spirit loose. He’s terrified, and rightfully so, but his sacrifice is the "noble" path here.
One detail people often miss is the connection to the larger world. The Catriona plague isn't just some random sickness; it's a major plot point in the Witcher books, brought over from another world by Ciri’s accidental jumping. Seeing the "Plague Maiden" manifestation on Fyke Isle bridges the gap between the games and Sapkowski’s original writing in a way that feels seamless.
Final Insights for the Aspiring Witcher
Don't let the fog of Fyke Isle fool you. A Towerful of Mice is a test of your instincts as a player.

If you want to walk away from this quest with the best possible outcome, your next steps are clear. First, head back to the mainland and find Graham in his hut near Oreton. Be honest with him. He’s a broken man, but he’s the key. Escort him back to the tower—and keep your silver sword drawn, because the monsters you cleared earlier might have friends.
Once you’re inside, let the scene play out. It’s uncomfortable to watch, but it’s the only way to ensure the curse is truly lifted. After the dust settles, don't forget to report back to Keira Metz. Her reaction to your choices will influence your relationship with her later in the game, specifically during the "A Favor for a Friend" quest and the eventual battle at Kaer Morhen.
The beauty of The Witcher 3 is that even a small island in the middle of a swamp has a history worth uncovering. Just maybe... watch your step around the rats.
